The M/S Thor Liberty sailed from the north German port of Emden on Dec. 13 and two days later docked in Kotka, southern Finland, to pick up a cargo of anchor chains, Finnish Customs spokesman Petri Lounatmaa said.
Investigating officers didn’t know the origin of the Patriot missiles or who was supposed to receive them, he said.

“We have impounded the explosives and missiles and asked the Defense Ministry to transport and store them,” Lounatmaa said. “At this stage we don’t know where it (the cargo) was loaded on the ship or if the Thor Liberty planned a drop before its port of destination in China.”
